The invention relates to a safe, reliable and intelligent solar mosquito killing lamp applicable to an outdoor environment. The solar mosquito killing lamp comprises two mosquito killing mechanisms, the mosquito killing mechanisms comprise lifting mechanisms and mosquito killing boxes, driving units are arranged at the two sides of each mosquito killing box, the mosquito killing boxes are providedwith cross plates, baffles, concave openings, cleaning mechanisms and collecting grooves, each concave opening is internally provided with a power grid and several lamp tubes, and each cleaning mechanism comprises a third motor, a third driving shaft, several brushes and two translation components. According to the safe, reliable and intelligent solar mosquito killing lamp applicable to the outdoor environment, the driving units drive the baffles to rotate downwards to cover the surface of the concave openings in rainy weather, rainwater is prevented from hitting the power grids, a short circuit is not caused, the lifting mechanisms make the mosquito killing boxes lift, children are prevented from touching the power grids, a safety accident is not caused, and the safety of equipment is improved; besides, the cleaning mechanisms automatically clean the power grids, so that mosquito dead bodies fall into the collecting grooves, people's time is saved, cleaning is facilitated, and therefore the practicability of the equipment is improved.
